Fluent Bit is distributed as td-agent-bit package and is available for the latest stable CentOS system. This stable Fluent Bit distribution package is maintained by Treasure Data, Inc.
We provide td-agent-bit through a Yum repository. In order to add the repository reference to your system, please add a new file called td-agent-bit.repo in /etc/yum.repos.d/ with the following content:
[td-agent-bit]name = TD Agent Bitbaseurl = https://packages.fluentbit.io/centos/7/$basearch/gpgcheck=1gpgkey=https://packages.fluentbit.io/fluentbit.keyenabled=1
note: we encourage you always enable the gpgcheck for security reasons. All our packages are signed.
Once your repository is configured, run the following command to install it:
$ yum install td-agent-bit
Now the following step is to instruct systemd to enable the service:
$ service td-agent-bit start
If you do a status check, you should see a similar output like this:
